Hi
When I compile it I will get following erros :

Hi @golizheh

Seems that colcon is being unable to locate Fast-RTPS. Did you execute the 'install/local_setup.shscript before thecolcon buildcommand? If so, try addingfastrtps` to the packages select.

Hi @LuisGP
Thanks for your answer,
Could you please explain a little more adding Fastrtps to command?
I have run follwoing command:
colcon build --cmake-args -DTHIRDPARTY=ON --packages-select firos2 Fast-RTPS

I have FAST RTPS on my /ros2_ws/src/eProsima

But it is seems like it is ignoring to run WARNING:colcon.colcon_core.package_selection:ignoring unknown package 'Fast-RTPS' in --packages-select.
Should I install and run something before?

[LuisGP]

Try the following:

colcon build --cmake-args -DTHIRDPARTY=ON --packages-select firos2 fastrtps

[golizheh]

Unfortunately same error:

:~/ros2_ws$ colcon build --cmake-args -DTHIRDPARTY=ON --packages-select firos2 fastrtps
Starting >>> fastrtps
Finished <<< fastrtps [8.36s]
Starting >>> firos2

Hi @golizheh,

The most updated branch of FIROS2 (feature/TCP_DynTypes) is from December 2018 so the last supported ROS2 version is Crystal.

I tested that branch with Crystal and it compiles successfully.

We will merge feature/TCP_DynTypes into master and we will update the README.

Sorry for the inconvenience.

Thanks @LuisGP for your updating, it is works fine.
